PLOW.

SPECIFICATION forming part of Letters Patent No. 408,331, dated August6, 1889.

l Application filed April 2, 1888. Renewed June 25, 1889. Serial No.315,509. (No model.)

T0 @ZZ whom, may concern.-

Be it known that I, AUGUST JACOB VENTZKI, a subj ect of the King ofPrussia, German Emperor, and a resident in the city of Graudcnz, in theKingdom of Prussia, Germany, have invented certain new and usefulImprovements in Plows, of which the following is a full, clear, andexact specification. y

This invention relates to plows which can be made to work either withone share or with two or more shares, and is distinguished from otherimplements of a like nature lby the facility with which the furrow andthe supporting-wheels can be shifted by means of a lever, and also by adevice for applying the pull at any required point, so that the plow canalways be drawn in a straight line.

In the drawings which form a part of this specication, Figure l is aside elevation of the plow in position for working; Fig. 2, a sideelevation ofthe plow in a position ready for transport; Fig. 3, a plan;Figs. 4C to 7, details of the plow.

The main frame R, Figs. l to 3,rests on the bearings of the bent axles aa', on which the furrow-wheel F and the supporting-wheel L arerespectively mounted. These two axles are so moved by the lever W thatthe axle a of the supporting-wheel is moved a greater distance than theaxle ce', and the depth of the furrows determined by the difference ofthe positions of the front wheels.

Both arms s and s of the lever WT, which move the twoaxles by means ofthe connecting-rods S and S', the latter being connect-cd with the axlea through the medium of arm 7L', are so situated that the arm s is atthe dead-point when the furrow-wheel has attained its properposition-that is to say, the horizontal plane of the sole of theplowshare. Now, as in this position, Fig. l, the motion -of thefurrow-wheel is very small, owing to the arm s being in the neighborhoodof the dead-point, and as at the same time the motion of the arm s,connected to the axle of the supporting-wheel, is at its maximum, analteration in the height of the wheels in respect tc each other is theresult, and the depth of the furrows is determined by simply moving thelever XV.

The axle a of the furrow-wheel is capable of sliding in theAguiding-blocks f and in the regulating-rin g h. This cont-rivance allowsthe distance between the furrow-wheel and the supporting-wheel to beincreased, so that a plow with one share can be provided with twoshares, if desired. (See dotted lines, Figs. l and 3.) In this case theright-hand. wheel is shifted (see dotted lines) so as to travel in thefurrow without coming out of engagement with the lever mechanism. Thewheel F could, if desired, be shifted on the axle, (instead of the axlebeing movcd,) in order 'to alter the distance apart of the wheels, inwhich case the straight part on which the wheel is mounted is madelonger.

Both connecting-rods S and S, which transmit the motion of thehand-lever W to thc axles, are divided in the middle, (see Figs. 4 and5,) and the length of these two parts can be adjusted by means of boltst' and z" in the following manner: 1n one half there is an elongatedhole or slot, in which the bolts can be made to slide. By tightening thebolt the projection n on t-he one half of the connecting-rod engages oneof the notches made on the other half. 1n this manner both ends of theconnecting-rod can be joined together, so as to be capable of being-adjusted.

The draft-bar z, Fig. 6, made, preferably, of T-ircn, is arranged so asto be capable of adjustment on the cross-piece of the framing by meansof the claw 7s and adjusting-bolt e. At the rear end the draft-bar canbe fixed by means of bolts or pins inserted through one of the holes ofthe arm Z and the rack. In consequence of this arrangement it ispossible to iix the draw-gear in any required position, no matter whatis the space between the wheels. It can be shifted to the right or tothe left, up -or down, forward orA backward, parallel or diagonally tothe main framing. If, for instance, three horses are employed forcutting more than one furrow, the traction-line is on the left towardthe outside of the main framing, and the draft-bar 2 must be placeddiagonally, (the dotted lines in Fig. 3 show this position,) asotherwise the horseswould draw the share toward the side of the land,

and thereby make the furrows broader .and

broader. On the contrary, when the draft-bar is placed in a diagonalposition, the plowshare will be drawn exactly in the direction of thefurrows. By means of this draw-gear the plow is drawn along in astraight line with a loose chain, whose point of application is withinthe limits of t-he frame. The plow is Iby this arrangement drawn alongsafely not onlyin plowing and turning up flat land with one or moreplowshares, but also hilly surfaces. The turning of the plow is alsorendered more easy by the use of this draw-gear.

Having now particularly described and ascertained the nature of the saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is- 1. In a plow, the axles a a', forming knees for the twofore wheels L F, which can be moved by an angle-leverW, provided withtwo arms, by means of adjustable driving-rods S S', so that thedifferent large adjustments of the two wheels enable the determinationof the depth of the furrow, whereby the arm of the angle-lever whichplaces the furrowwheel in position stands on the dead-point as soon asthe wheel has obtained its correct position, in order to enable theplacing and lisplacing of the plow by means of one single ever.

2. The combination, in a plow, of the axle CL', adjustable in thedirection of its length, and the axle a of the furrow-wheel, for thepurpose of changing the distance of the two fore wheels as may benecessary, and aframe adapted to carry one or two plows, and thus totransform a one-shared plow into a twoshared plow in such manner thatthe furrowwheel can in each case be placed in the last furrow and can bekept by this in its correct position` 3. In a plow such as described,the combination, with the furrow-wheel F, the bearings f, theregulating-ring h, and the arm h', of an axle a', which is capable ofbeing adjusted in the direction of its length within said bearings andring, for the purpose of using the plow as a single or double shareplow, in such a manner that in both modes of working the furrow-wheelcan always be placed in the furrow last made, so as to be guided by it,substantially as set forth.

4. In a plow such as described, the connecting-rods S S', which can beadj usted as'regards their length and made to transmit the motion of thelever W to the axles a a, for the pur-- pose of adjusting the positionof the wheels with respect to each other, in combination with said leverand its differently-located arms s s', substantially as set forth.

In testimony whereof Ihave signed my name to this specification in thepresen ce of two subscribing witnesses.

AUGUST JACOB VENTZKI.
